RESUMO
BACKGROUND: Inflammation and the immune system significantly impact the development, progression, and treatment response of hepatocellular carcinoma (HCC). This retrospective study investigated the neutrophil-to-lymphocyte ratio (NLR) as a prognostic biomarker in Western patients with HCC in the setting of chronic viral hepatitis. METHODS: Patients diagnosed with HCC from 2005 to 2016 were selected from a tertiary care institution. NLR was calculated within 30 days prior to treatment and dichotomized at the median. Kaplan-Meier overall survival (OS) curves and Cox hazard proportional models were utilized. Tumor and liver reserve parameters were included in multivariable analyses (MVA). RESULTS: A total of 581 patients met inclusion criteria (median age 61.0 yr; 78.3% male; 66.3% Caucasian) with median OS = 34.9 mo. 371 patients (63.9%) had viral hepatitis, of which 350 had hepatitis C (94.3%). The low-NLR group (Assuntos

RESUMO
PURPOSE: Thermal ablation (TA) and transarterial chemoembolization (TACE) may be used alone or in combination (TACE+TA) for the treatment of hepatocellular carcinoma (HCC). The aim of our study was to compare the time to tumor progression (TTP) and overall survival (OS) for patients who received TA alone or TACE+TA for HCC tumors under 3 cm. MATERIALS AND METHODS: This HIPAA-compliant IRB-approved retrospective analysis included 85 therapy-naïve patients from 2010 to 2018 (63 males, 22 females, mean age 62.4 ± 8.5 years) who underwent either TA alone (n = 64) or TA in combination with drug-eluting beads (DEB)-TACE (n = 18) or Lipiodol-TACE (n = 3) for locoregional therapy of early stage HCC with maximum tumor diameter under 3 cm. Kaplan-Meier analysis was performed using the log-rank test to assess TTP and OS. RESULTS: All TA and TACE+TA treatments included were technically successful. TTP was 23.0 months in the TA group and 22.0 months in the TACE+TA group. There was no statistically significant difference in TTP (p = 0.64). Median OS was 69.7 months in the TA group and 64.6 months in the TACE+TA group. There was no statistically significant difference in OS (p = 0.14). The treatment cohorts had differences in AFP levels (p = 0.03) and BCLC stage (p = 0.047). Complication rates between patient groups were similar (p = 0.61). CONCLUSION: For patients with HCC under 3 cm, TA alone and TACE+TA have similar outcomes in terms of TTP and OS, suggesting that TACE+TA may not be needed for these tumors unless warranted by tumor location or other technical consideration.

BACKGROUND: Percutaneous drainage is a first-line treatment for bilomas developed post-cholecystectomy in the setting of bile leak from the cystic duct stump. Percutaneous drainage is usually followed by surgical or endoscopic treatment to address the leak. AIMS: This study aimed to evaluate outcome of selective coil embolization of the cystic duct stump via the percutaneously placed drainage catheters in patients with post-cholecystectomy bile leak. METHODS: Seven patients with persistent bile leak after laparoscopic cholecystectomy who underwent percutaneous catheter placement for biloma/abscess formation in the region of the gallbladder fossa were followed. These patients underwent selective trans-catheter cystic duct stump coil embolization from Feb 2013 to Feb 2019. Procedural management, complications, and success rates were analyzed. RESULTS: All patients underwent placement of a percutaneous catheter for drainage of biloma formation in the gallbladder fossa post-cholecystectomy. Selective coil embolization of the cystic duct was performed through the existing percutaneous tract on average 3.5 weeks after percutaneous catheter placement, resulting in resolution of the biloma. All bile leaks were immediately closed. None of the patients showed recurrent bile leak or further clinical symptoms. Coil migration to the common bile duct was diagnosed in a single case, after 2.5 years, with no bile leak reported. CONCLUSIONS: Selective trans-catheter coil embolization of the cystic stump is a feasible and safe procedure, which successfully seals leaking cystic duct stumps and can circumvent the need for repeat surgical or endoscopic intervention in selected patient populations.

BACKGROUND: Hyperimmunoglobulin E syndrome (HIES) is a rare primary immunodeficiency disorder defined by high serum immunoglobulin E titers that is associated with recurrent respiratory infections, formation of pneumoatoceles, recurrent skin abscesses, and characteristic dental and skeletal abnormalities. CASE PRESENTATION: We report a case of a 56-year-old male with a history of HIES, cavitary mycetomas, and allergic bronchopulmonary aspergillosis who presented with recurrent massive hemoptysis. Bronchial artery angiography and bronchoscopy failed to identify active hemorrhage, and two embolizations of the bronchial artery did not resolve the bleeding. Subsequently, selective pulmonary artery angiography was conducted that demonstrated a subsegmental pulmonary artery branch pseudoaneurysm with extravasation into an adjacent lung cavity. This was treated successfully with transcatheter embolization. CONCLUSIONS: To our knowledge, this is the first case reported of pulmonary artery pseudoaneurysm in HIES in the medical literature. Pulmonary artery pseudoaneurysm should be considered in the differential diagnosis in patients with HIES and massive hemoptysis.

Image-guided percutaneous local and regional modalities are major treatments for hepatocellular carcinoma. Patients having better liver function and performance are usually eligible and can gain significant survival benefit, especially with more limited tumor burden. The most common local therapies are ethanol and radiofrequency ablation, with the latter providing better local tumor control and survival. Radiofrequency ablation has also occasionally been found to be equivalent to surgical resection for appropriate tumors, with additionally lower morbidity. Chemoembolization is the prevalent transarterial therapy and has been shown to increase survival compared with conservative management. Chemoembolization using drug-eluting beads and radioembolization with ß-emitting yttrium-90 microspheres seems to reduce side effects and expand the pool of eligible patients, whereas controversy remains regarding the role of bland particle embolization. Combinations of local and regional therapies may be appropriate for treating a particular tumor or different tumors over time and they may be combined with surgical and medical options.

PURPOSE: To test the hypothesis that not all embolic materials are equivalent by using postprocedural magnetic resonance (MR) imaging enhancement of uterine fibroids in patients treated with uterine artery embolization (UAE). MATERIALS AND METHODS: Approval and a waiver of consent from the institutional human investigations committee was received for this study. The study was HIPAA compliant. A total of 84 women who underwent 6-month MR imaging follow-up constituted this retrospective study. Within this group, 25 women were treated with Contour polyvinyl alcohol (PVA) particles, 23 were treated with Contour SE particles, 19 were treated with Embosphere microspheres, and 17 were treated with Bead Block microspheres. Pre- and postprocedural MR imaging results were analyzed for the total number of fibroids present in the uterus of each patient and for the percentage of individual fibroid enhancement. Enhancement of individual fibroids was measured with quartile intervals. Greater than 25% residual enhancement of a fibroid after embolization was considered an incomplete infarction. The overall percentage change in enhancement was calculated for each patient. Bivariate analysis by using generalized linear modeling and one-way analysis of variance was used to assess differences in infarction with different embolic materials. RESULTS: Among patients treated with Contour and Embosphere, there was a mean reduction in enhancement by 76.60% and 83.07%, respectively, compared with a mean reduction of 52.53% and 49.78% in patients treated with Bead Block and Contour SE, respectively. There was a significant difference in postembolization enhancement between Bead Block and Embosphere, Bead Block and Contour, Contour SE and Embosphere, and Contour SE and Contour. CONCLUSION: Patients treated with Bead Block or Contour SE demonstrated a reduced degree of infarction at follow-up MR imaging compared with patients treated with Contour or Embosphere.

Malignant pleural effusions (MPEs) are commonly seen as complications of advanced malignancy, especially in lung cancer and breast cancer. The management will depend on the performance status of the patient, severity of the symptoms, and the primary tumor's response to systemic therapy. Thoracentesis is usually the first step for both diagnostic and therapeutic reasons. Chest tube placement with sclerotherapy is successful in 60 to 90% of cases, but it requires hospitalization for ~1 week. Alternatively, long-term tunneled pleural drainage catheters can be performed on an outpatient basis and are effective in controlling symptoms in 80 to 100% of patients. Additional advantages are the ability to treat trapped lung, large loculated effusions, and bilateral effusions simultaneously, as well as lower charges. Spontaneous pleurodesis can occur in up to 50% of the patients. Tunneled catheters should be considered in all patients with MPE and particularly those who have a reasonable expectancy of being outpatient.

Chronic venous insufficiency (CVI) is an exceedingly common and underdiagnosed disorder with a wide range of symptoms and prognosis ranging from cosmetic issues to skin ulceration with tissue loss. Ultrasound plays a pivotal role in the diagnosis, classification, and guidance of percutaneous treatment of CVI. It is therefore of critical importance to the practicing radiologist to have a sound understanding of the pathophysiology, pertinent venous anatomy, and classification of CVI. We review the superficial and deep venous anatomy of the lower extremity, introduce a pattern recognition approach for mapping of varicosities, and review the protocol for ultrasound evaluation for CVI. In addition, we discuss the pathophysiology of CVI and the role of ultrasound in guidance for and follow-up of percutaneous treatment.

Malignant pleural effusion is a significant cause of morbidity and a poor prognostic indicator. Traditional treatments have variable success and significant drawbacks, including a length of stay in the hospital. Alternatively, a tunneled pleural catheter permits long-term drainage as an outpatient, cost-effectively controlling the effusion and related symptoms in over 80 to 90% of patients. Other advantages are the ability to treat trapped lungs and large locules. Spontaneous pleurodesis may occur in over 40% of patients, and the catheter can be used to administer sclerosant or antineoplastic agents. Complications tend to be minor and easily managed. A tunneled pleural catheter should be considered for all patients with MPE having a reasonable expectancy of being an outpatient.
